Double-quantum two-dimensional electronic spectroscopy of a three-level system: Experiments and simulations

Original language description

Combining Double-quantum coherence two-dimensional (2Q2D) electronic spectroscopy with single-quantum two-dimensional (1Q2D) electronic spectroscopy enables one to determine the strength of the excited state absorption transition and the relative detuning of electronic states, as well as the dynamics of the single-quantum coherence. The 2Q2D spectrum reveals three peaks of alternating signs with the major negative peak located at higher frequencies along the emission axis compared to the single positivepeak. The 1Q2D spectrum, on the other hand, shows a negative peak stemming from excited state absorption at lower frequencies along the emission axis. Employing a three-level model in which all time correlations of the third-order response function areaccounted for via second-order cumulant expansion gives good agreement with both the 1Q2D and 2Q2D data.
